TO ALL WHOM IT MAY CONCERN:

Be it known that I, FREDERICK VAN PAT'rnN, of Auburn, in the county of Cayuga, and State of New York, have invented certain new and useful Improvements in a Fifth-Wheel or Whittie-tree Connection or Attachment for Carriag-es, and that `the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specication, in which- Figure l represents a section through a portion of an axle-tree and perch to show the connection.

Figure 2 represents a top view of the under plate of coupling or connection; and

Figure 3 represents similar views of the upper plates thereof. v

Similar letters of reference, where they occur in the separate gures, denote like parts in all the drawings.

My invention consists ina iith-Whccl or Whittle-tree connection that will turn freely but cannot part or separate, and composed lof an under plate having a flanged sleeve upon it, and a sectional upper plate with half collars to surround the neck of the sleeve or hub, both plates being secured to their respective parts by screws, so as to be readily placed, removed, and replaced, as occasion may require.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to thc drawings.

A may represent an axle or cross-bar, and D a perch or whiiie-tree, thc two connected by my coupling plates, hs shown in the section, tig. I. The plates are made. as follows: C is the under plate, having a hub, a, rising from it, the top of which has a iange or rim, In, upon it. In this plate are screw-holes, c c, to secure it to the axle or cross-har A. The upper plate is composed of two sections, D D. The one, D, has a half collar, CZ, surrounding n circular opening, e, in it, andan cpening,f, that will receive the other scction,D, in it. The section D has also a half collar, (I, upon it, which surrounds a circular opening, c, in it, as in the other section. vWhen the plate D is slipped up against the neck a and the plate Dl slipped into the openingfot` the plate D and against thc neck a, the two halt` collars completely surround the neck a under the flange And when screws are inserted through the holesgg into the pieceB, the two pieces A B are inseparably connected together, while they are free to turn one upon the'other. The perch or Whittle-tree B has a hole bored into it to receive the hub and, collar of the under and upper plate and allow the two plates to bear and turn upon each other. Inv

some couplings or connections the upper and under plates may be reversed and an opening, z', made through the hub to receive n bolt or other through fastening.

Having thus fully described my invention, what I claim as new, and desire to secure hy Letters Patent, is A fifth-wheel or ivhifiie-tree connection for carriages, composed of plates C D D, with the hub and collars, constructed and operating substantially as and for the purpose described.
